Benefits of synchronizing ovulation with porcine luteinizing hormone in a fixed-time insemination protocol in weaned multiparous sows
Double insemination of multiparous sows, timed to coincide with optimal sow fertility, may improve litter size.

Organization of the replacements II
In previous chapters we have looked at the importance of maintaining the ideal parity profile within each batch.
Effects of space allowance and floor type on gaseous emissions from gestating sows
This study aims to compare emissions of pollutant gases (NH3, N2O, CH4, CO2) from gestating sows kept on straw based deep litter depending on the space allowance and the floor type.
Gestation in stalls
This month we are setting you a new test, in this case on the welfare of sows accommodated in stalls during gestation.
Sow parity structure (I)
One of the main goals for a sow herd is to achieve a correct homogeneity of the productive batches.
Jyden Bur: Free stall system for the European market
As of 2013, the European Union has made new requirements for gestated sows. The ordinary static crate will be phased out by law but there are other solutions. A high level of efficiency, an improved working environment and more animal welfare is the outcome of the popular and flexible gestation crate, JB5000 from Jyden Bur – a Danish company with an international perspective.
Conditions for gestating sows in groups
A new instalment of the test on animal welfare in swine herds. This test evaluates your knowledge on the welfare of gestating sows allotted in groups.
Dimension and design of the farrowing unit
The Danish pig producers’ research organisation has tested a number of different designs. They recommend pen dimensions of 2.7x1.8 m to accommodate modern prolific breeds.
Management of the breeding chart (II)
In the first part of management of the breeding chart we basically looked at how it can help us to control returns. In this second part we will look at other applications.
Farrowing programming (I)
In this chapter we will look at how hormones can be used to influence the time of farrowing according to our needs.
Diagnosis of Porcine Respiratory and Reproductive Syndrome
In reproductive disease, submission of several whole affected litters is advisable to provide material for diagnosis of PRRSV and other diseases causing reproductive or neonatal problems.
Dimension and design of the gestation unit
The gestation unit is basically a parking unit where sows should be kept comfortable to allow the pregnancy to develop
Hormone management (II)
When the sow is pregnant, the corpus luteum remains and continues to produce progesterone. While the levels of progesterone are high the sow does not become in heat and maintains gestation.
Maternal Nutrition and Foetal Development
Low maternal feed levels cause a reduction in muscle fibre numbers, whereas enhanced maternal nutrition resulted in a higher number of muscle fibres in specific muscles.
Pork CRC: Award winning pig egg cells
Vital research to reduce seasonal infertility, an ongoing problem for Australia’s pig industry, has been rewarded with a 2009 Science and Innovation Award for Michael Bertoldo, a Pork CRC supported PhD student at The University of Sydney.
PRRS Eradication: A dream or missed opportunity?
Since 1987, Porcine Reproductive and Respiratory Syndrome virus (PRRS) has become a global drain on pig productivity, profitability, and many a producers’ morale. One thing that remains certain is PRRS virus continually finds ways to circumvent our best bio-management efforts. PRRS marches on in a ceaseless continuum of antigenic change making current vaccines and other control techniques of limited value.
